Combine dry ingredients and rub meat with mixture.

Place meat in crock pot.

Combine barbeque sauce, vinegar and Worcestershire sauce. Pour over meat.

Cover and cook on low 10 to 12 hours.

Remove meat, shred.

Pour meat juices into a fat strainer. If you don't have one pour into a container, let cool, then put in freezer long enough to solidify the fat for easy removal(keep meat warm when doing this). Add juices as desired.
